6286ce1d16 Store column number for aliases, defaults and userspecs too. 
This is used to provided the column number along with the line
number in error messages.  For aliases we store the column of the
alias name, not the value since that is what visudo generally needs.

d899fe5936 Use real setters for the eventlog config. 
This makes it possible to have a base config that the callers can
modify instead of replacing the config wholesale.

10d3d69aa1 Pass a struct to the match functions to track the resolved command. 
This makes it possible to update user_cmnd and cmnd_status modified
by per-rule CHROOT settings.

b6dbfe5094 Take the chroot into account when search for the command. 
This could a a user-specific chroot via the -R option, a runchroot
Defaults value, or a per-command CHROOT spec in the sudoers rule.

1676f0ceeb Support "*" for CWD/CHROOT to allow user to specify cwd or chroot. 
Adds two new command line options, -D (--chdir) and -R (--chroot)
that can only be used when sudoers sets runcwd or runchroot to "*".

6bdfd010d2 Add CHROOT and CWD sudoers options. 
Also matching runchroot and runcwd Defaults settings.

446ae3f507 Include string.h unconditionally and only use strings.h for strn?casecmp() 
In the pre-POSIX days BSD had strings.h, not string.h.
Now strings.h is only used for non-ANSI string functions.

dd88460800 We no longer need to include headers we don't use for sudo*.h files. 
Previously we needed to include headers required by the various
sudo*h files.  Now those files are more self-sufficient and we
should only include headers needed by code in the various .c files.

8186b98208 Adapt sudoers iolog client to log server dual port changes. 
The TLS handshake now occurs before the ServerHello message is read.
This fixes potential man-in-the-middle attacks and works better with
TLS 1.3.

df8f06609c Add a new flag "allow_unknown_runas_id" to control matching of unknown IDs. 
Previous, sudo would always allow unknown user or group IDs if the
sudoers entry permitted it.  This included the "ALL" alias.
With this change, the admin must explicitly enable support for unknown IDs.

171686c422 update_defaults() needs to be able to take a defaults_list for 
the ldap/sssd backends which support per-role defaults.

70d519c8ad o Move userspecs, defaults and aliases into a new struct sudoers_parse_tree. 
o The parse tree is now passed to the alias, match and defaults functions.
o The nss API has been changed so that the nss parse() function returns
  a pointer to a struct sudoers_parse_tree which will be filled in
  by the getdefs() and query() functions.

f9be3a48a2 Simplify the nss interface such that each sudoers provider fills 
in a per-nss list of userspecs and defaults instead of using separate
lookup and list functions.  This makes it possible to have a single
implementation of the code for sudoers lookup and listing.

71e98d9493 Include parse.h in sudoers.h since it will soon be required. 2018-05-14 09:05:02 -06:00

bc5e2d06a7 Add free_default() to free a struct defaults pointer so we have a 
single place where we free the defaults.  A pointer to the previous
Default's binding may be passed in to avoid freeing an already free
binding.

bcfb092a4e Convert from time in minutes to timespec directly instead of 
converting to double via strtod().  This makes it easier to catch
overflow.

4c0c225062 Store passwd_timeout and timestamp_timeout as a struct timespec 
instead of as a float.  Remove timeout argument to auth_getpass()
as it was never used.

b16912da1d Don't include syslog.h from logging.h, just include it in the two
